    摘要: Disclosed is a computer implemented method, computer program product, and apparatus to establish at least one paging partition in a data processing system. The virtualization control point (VCP) reserves up to the subset of physical memory for use in the shared memory pool. The VCP configures at least one logical partition as a shared memory partition. The VCP assigns a paging partition to the shared memory pool. The VCP determines whether a user requests a redundant assignment of the paging partition to the shared memory pool. The VCP assigns a redundant paging partition to the shared memory pool, responsive to a determination that the user requests a redundant assignment. The VCP assigns a paging device to the shared memory pool. The hypervisor may transmit at least one paging request to a virtual asynchronous services interface configured to support a paging device stream.

    摘要: An apparatus and method selectively invalidate entries in an address translation cache instead of invalidating all, or nearly all, entries. One or more translation mode bits are provided in each entry in the address translation cache. These translation mode bits may be set according to the addressing mode used to create the cache entry. One or more “hint bits” are defined in an instruction that allow specifying which of the entries in the address translation cache are selectively preserved during an invalidation operation according to the value(s) of the translation mode bit(s). In the alternative, multiple instructions may be defined to preserve entries in the address translation cache that have specified addressing modes. In this manner, more intelligence is used to recognize that some entries in the address translation cache may be valid after a task or partition switch, and may therefore be retained, while other entries are invalidated.
